Answer: 2.850

Explanation:

$19.32=\frac{55.07}{v}\\19.32v=55.07\\v=\frac{55.07}{19.32}=\boxed{2.850 \text{ mL}}$

Rank these compounds by highest boiling point to lowest boiling point? Pentane, neopentane, isopentane

PilotLPTM [1.2K]

Pentane has a boiling point of 36.1 C, while isopentane boils at 27.7C. Neopentane has the lowest boiling point at 9.5 C. Therefore from highest to lowest boiling points, it is pentane, isopentane, and neopentane.

Consider the first-order reaction described by the equation At a certain temperature, the rate constant for this reaction is 5.8

zubka84 [21]

Answer: The half life of the reaction is 1190.7 seconds

Explanation:

The equation used to calculate rate constant from given half life for first order kinetics:

$t_{1/2}=\frac{0.693}{k}$

where,

k = rate constant of the reaction = $5.82\times 10^{-4}s^{-1}$

$t_{1/2}$ = half life of the reaction = ?

Putting values in above equation, we get:

$t_{1/2}=\frac{0.693}{5.82\times 10^{-4}s^{-1}}=1190.7s$

Hence, the half life of the reaction is 1190.7 seconds
